im pretty sure chemical weapons were not used in ww2 at all
The germans were to scared to use it on the US cause they had intel that the US had stuff to throw back. Im pretty sure that they tried to use the m on the British but it wasnt trench warfare anymore so it didnt work.
I still dont see a problem with the flamethrower squad, Im not asking to make the super troops, just standard squad , my pioneers get killed by anything and everything.
